Abstract
The Telegraph equations have been used to obtain expressions for the following quantities in an attenuating electric transmission line:
1. the input impedance in terms of the length of an open-circuited line,
2. the modulus of the voltage as a function of the distance along an open-circuited line,
3. the ` apparent phase velocity at a point ' along a line, as a function of the distance from the origin and the nature of the termination,
4. the ` apparent phase velocity over a finite interval ' for the same type of line,
5. the modulus of the reflection coefficient in terms of (4).
Numerical examples have been computed for (1)-(4) and are presented.
The use of the attenuating electric line as a model in approaching an understanding of the dynamics of the arterial circulation is outlined, and the limitations discussed.
